The invention relates to anti-freezesolutions and processes for making the same.

The invention particularly relates to the production of a solution of this type from a brine solution as the main component which has mixed therein and incorporated as essential components thereof, glycerine, a dissolvant thereof such as wood or denatured alcohol and liquid colfee.

While a brine formed by dissolving calcium chloride in water is well known as a soto the solution certain favorable characteristics. v

The solution which is the subject of the present invention tends to absorb and thereby remove rust from the section containing the solution, it tendsto prevent the formation of rust in said section and also to prevent the formation of lime deposits and all of this, without injury to the metal parts with which the solution contacts.

A preferred mode of realizingthe inven-. tion is hereinafter described but it will be understood that, according tothe broader as- 'the exact proportions herein pects thereof, the invention is not limited to specified, but; the proportions may be varie depending upon the commercial characteristics of the particular ingredients employed and also upon the characteristics of the service for which the particular solution is intended.

A preferred formula for producing the solution is as follows; namely, for roducmg 100 gallons of the solution, there is employed one-half gallon of glycerine, one-half gal lon of wood or denatured alcohol, 260 pounds of calcium chloride and liquid coifee derived from thoroughly boiling two pounds of coffeePeaberry coflee, the coifee being Application filed January 18, 932. Serial No. 587,450.

boiled three times, each time in five gallons of water and then adding enough water to make I the 100 gallons.

In the preferred form of carrying out the invention, a heavy brine isfirst produced by dissolving the calcium chloride in water. Thereto, there is mixed the glycerine, preferably mixed in and dissolved by one-half gallon of the alcohol, and, into brine in which the glycerine-alcohol mixture has been incorporated, there is supplied the liquid ex tracts derivable from the coffee by the boil ing methods above outlined.

Ap' licant believes that a chemical reaction takes place when the elements are brought together. This is evidenced by the fact that the resulting liquid becomes hot and to a certain extent.

Some of the characteristics of the solution which results from carrying out the process above described, are as follows:

foams The solution will not freeze at 40 below I 'zero-Fahrenheit scale.

The solution dissolves alllime in the radiator,-if used in an automobile radiator, and removes and prevents rusting'therein.

The solution does not have an injurious effect on the metal parts with which it comes in contact. Moreover, it does not effect the,

paint or enamel on the hood of automobiles, or elsewhere. I V

The solution serves as a good defroster in that it readily removes ice from the windshield of an automobile and tends to prevent the forming of ice on the Windshield when the solution is applied thereto.

1 It can be produced at relatively'low cost and is less volatile than water.

It is diflicult to state with certainty all the functional advantages incident to the use of the cofiee but applicant believes the coffee is the dissolving agent, or an essential part thereof, that dissolves and prevents the for- 'mation of lime.

The purpose of the glycerine is to oil the surface with which it comes in, contact and in this way, it largely prevents the formation of rust.

As above indicated, the alcohol thins or dissolves the glycerine.

- by dissolving' 260 What is claimedjs: v

1. The process of forming an anti-freeze solution which comprises producing a brine in water, adding to the brine 'one gallon of glycerine dissolved in one-half gallon of alcohol and mixin coffee extract erived by boiling two pounds of coffee in water, and adding sufiicient water to make 100 gallons. i

2. The process of forming a solution of the .class and for the purposes described which comprises mixing with a heavy brine solution of glycerine, alcohol and the liquid extracts derivable from coflee by boiling the same in water. 3. In the forming of anantisfreeze solution the process which comprises the mixing of water, glyoerine, calciumj chloride, alcohol and ljgillid extracts derivable from coffee.

coflee extract;

5. An anti-freeze solution comprising 260 pounds of calcium chloride, in approximately 100 gallons of water, one-half gallon of glycerine, one-half gallon of-alcohol, and the liquid extracts derivable from cofi'ee.

In testimonywhereof, I have hereunto set my hand this 9th day of January, 1932.
